  Abstract  
  A series of benzyl chloride and amine group functionalized silsesquioxane particles were prepared by direct hydrolysis and co-condensation of their respective silane precursors. The size distribution of particles was controlled upon adjusting the molar ratios of organotrialkoxy silanes and base concentrations. Through selective post-functionalization with anthracene and rhodamine B, dual fluorescent particles were obtained. Morphologies, and optical properties of particles were revealed from TEM, SEM, fluorescence optical microscopy, and fluorescence spectroscopy. TEM and SEM images of particles revealed the average size and shape of the particles. The spectroscopic traces of functionalized particles in solution confirmed the covalent attachment of anthracene and rhodamine B with the emission ranging from 355 nm to 452 nm and 550 nm to 625 nm respectively. These resulting particles with binary reactive functionality are found to be advantageous due to the ability of selective functionalization with fluorescent semiconducting ligands of small molecules to semiconducting polymers to make multiplexed fluorescent colloids.
